DNS & Email Infrastructure

Validate your SMTP DNS configuration in real-time. Execute live DoH queries to audit MX routing targets, verify SPF authorization, and enforce strict DMARC policies.

Perform a strict Reverse DNS and FCrDNS audit in real-time. Execute live DoH queries to resolve IPv4/IPv6 ARPA mappings and verify mail server network identity instantly.

Perform a strict RDNS quality audit. Enforce FCrDNS integrity, detect generic cloud hostnames, and validate IPv6 reverse mappings in real-time via live DoH queries.

Generate flawless PTR records for BIND. Automatically format IPv4 in-addr.arpa and complex IPv6 ip6.arpa nibble expansions with proactive live FCrDNS validation.

Verify your mail server's reverse DNS instantly. Perform live DoH queries to check IPv4/IPv6 PTR records, validate ARPA mappings, and bypass strict anti-spam filters.

Verify your authoritative nameservers in real-time. Detect lame delegations, audit DNS redundancy, and ensure RFC compliance via live DoH queries.

Perform a real-time Mail Server Health Check. Automatically detect your primary MX and execute live TCP socket connections to audit Port 25, 465, and 587 availability.

Verify your mail server infrastructure in real-time. Analyze MX priority queues, perform deep IP resolutions, and detect critical RFC violations via live DoH queries.

Verify your SMTP HELO/EHLO greeting. Perform live forward and reverse DNS (PTR) lookups to ensure your mail server hostname aligns perfectly with its outbound IP.

Trace your complete email routing topology in real-time. Map MX failover paths, detect illegal CNAME redirects, and verify IPv6 mail readiness via live DoH queries.

Generate complete, RFC-compliant email DNS records instantly. Create MX routing, SPF policies, DMARC rules, and secure 2048-bit RSA DKIM key pairs for flawless deliverability.

Verify your email infrastructure in real-time. Perform direct DoH queries to validate MX routing, audit SPF authorization, and ensure strict DMARC alignment.

Perform an exhaustive DNS zone audit. Detect illegal apex CNAMEs, validate SOA parameters, and enforce strict RFC networking standards using live DoH queries.

Audit your DNS security posture in real-time. Validate DNSSEC against cache poisoning, enforce CAA policies, and verify DMARC anti-spoofing via live DoH lookups.

Perform a comprehensive DNS zone sweep. Fetch live A, AAAA, MX, NS, and TXT records using real-time DoH queries. Bypass cache for 100% accurate TTL and routing data.

Check DNS propagation globally in real-time. Verify A, AAAA, MX, CNAME, and TXT records across multiple worldwide resolvers to ensure your domain updates are live.

Perform a real-time DNS health check. Deep scan A, AAAA, MX, and NS records, verify nameserver redundancy, and get a live infrastructure health score.

Perform a holistic DNS email audit. Validate MX routing redundancy, analyze SPF strictness, enforce DMARC policies, and verify DKIM signatures using live DoH lookups.

Test your DNS configuration in real-time. Audit TTL values, verify IPv6 (AAAA) readiness, and detect CDN proxies using live DoH resolution.
